The Lemote Yeeloong rang a bell, since it's one of the few computers that's "built on free software from the BIOS up" that was recommended by Richard Stallman . Glad the effort to run this is still going strong and supporting the latest version of OpenBSD, released in May!
Interesting, I never heard that story before. Did he use full-disk encryption? One could presume that Stallman has signing keys for some GNU projects, so wouldn't the loss of his personal computer represent a major security issue?
(And yes, one could argue that a disk in an office or server could be stolen as well, whereas a laptop is in sight and loss is noted immediately, but I won't agree)
Also, MIPS has never been supported by Trisquel (another FSF-endorsed distro), and I suspect that since the lead Trisquel developer has since been hired as the senior sysadmin at the FSF, he gets some value out of giving RMS a laptop running Trisquel.
One issue I ran into was no pre-built packages for newer releases, so when I updated to 6.5 I had to downgrade to 6.3 to get any packages. Sans that, it's also unfortunate that Common Lisp implementations don't tend to support a MIPS that isn't under GNU/Linux; the GNAT compiler for Ada also isn't available. I can get GNU APL though, so that's nice.
Since some are wondering, I bought mine about eight years back for a few hundred dollars and even back then the website that supplied mine soon ran out of stock.
This article has reminded me that I'd intended to make pictures and descriptions of my Lemote Yeeloong available on my website months back, which is a great option for my 2019-09-09 article, so I'll do so.
Owning this machine has been a nice way to not use x86(_64) for everything and it's made me intent on my software working properly on less common machines and operating systems. My choices of language have likely already betrayed that, but I eventually intend to write implementations of my own and I'll ensure my Lemote Yeeloong is well supported. I also must remember that OpenBSD may not support it forever, although I could perhaps take over if it's ever necessary.
I could write more concerning this, but this seems sufficient.
I'd write it up, but I'm way to lazy^Wbusy right now.
Or if you want to go less standard (e.g. won't run Linux), get a modded PlayStation 1 :-)
As for a "more traditional computing" experience, you can always look for an SGI.
RISC-V borrows heavily from MIPS, so the two have a pretty similar development experience.
: https://github.com/frno7/linux or else source the official PS2 Linux Kit.
There's also the Digital Electronics "DecStation 5000" series that were R3000 and R4000 based, which could run Ultrix or probably some of the more modern BSDs.
They're probably rarer than used SGIs, but may be cheaper if you're lucky. (Though used 200MHz SGI Octanes are pretty cheap and plentiful in the US)
I am unsure what your point is.
